4. Remove sample from the sample well by absorbing with a
soft tissue.
5. Using plastic pipettes, rinse prism and sample well with
distilled or deionized water. Wipe dry. The instrument is ready
for the next sample.
8. MAKING A STANDARD % FRUCTOSE SOLUTION
To make a Fructose Solution, follow the procedure below:
y
Place container (such as a ZERO glass vial or dropper bottle
that has a cover) on an analytical balance.
y
Tare the balance.
y
To make an X Fructose solution weigh out X grams of high
purity Fructose (CAS #: 57-48-7) directly into the container.
y
Add distilled or deionized water to the container so the total
weight of the solution is 100g.
Note:
Solutions above 65% need to be vigorously stirred or shaken
and heated in a water bath to roughly 40 °C (104 °F). Remove
solution from bath when fructose has dissolved. Cool completely
before use. The total quantity can be scaled proportionally for
smaller containers but accuracy may be sacrificed.
